Plain-English meaning
Price Impact is used here to describe price movement associated with consuming available liquidity. In the daily board, the word is grouped by the role it performs rather than by spelling or market popularity.
You may encounter it in a product interface, technical document, risk report, policy paper, or market dashboard. The term is included for recognition and comparison, not as a product recommendation.
Important boundary
It is related to order size and depth, not just general market volatility.
When this word appears in a report, identify the mechanism being described before treating the label as a conclusion. Similar terms can point to different causes, controls, or outcomes.
Why it belongs with DEX Execution
Execution terms help describe how swaps are priced and why orders can fill at different prices than expected.
When solving the puzzle, compare the job this term performs with nearby cards. A correct group usually shares a function, risk type, workflow, or market structure rather than simply sharing similar wording.
Where you might see it
